Description

Technical Field

[0001] The utility model belongs to the technical field of replacing belts of belt conveyors, and particularly relates to a winch used for replacing belts of belt conveyors. Background Art

[0002] The primary equipment used to transport raw coal at the Sihe Mine Coal Preparation Plant is the belt conveyor, which boasts a compact structure, reliable operation, continuous transport, automated and centralized control, and easy maintenance. Our plant operates dozens of belt conveyors of varying sizes, each categorized by belt width: 1-meter, 1.2-meter, 1.4-meter, 1.6-meter, and 2.2-meter. Belt replacement is a major and frequent maintenance task at our plant.

[0003] For belt conveyors with a length of less than 50 meters, coal preparation plants previously mainly used the method of manually dragging the belts to remove the old belts and replace them with new ones. This method has problems such as a large number of participants, high labor intensity for employees, and long belt replacement time.

[0004] To solve the above problem, a stepless variable frequency winch was developed. This winch can achieve stepless speed adjustment, fast or slow. The stepless variable frequency winch is used to remove the old belt and replace it with a new one. Although it greatly saves manpower and reduces the labor intensity of employees, it also shortens the belt replacement time. However, when using the winch to replace the belt, after the old belt is dragged out a certain distance, the winch wire rope needs to be loosened by the same distance before the next round of towing can be carried out. The whole process is as follows:

[0005] Loosen the wire rope—connect the wire rope to the old belt—drag the old belt—remove the wire rope—loosen the wire rope (repeat several times).

[0006] During the process of replacing a new belt, the above process requires loosening the wire rope several times to complete the work of replacing the new belt. Each time the wire rope is loosened, the on-site maintenance personnel can only wait on the spot, which wastes time and prolongs the time for replacing the belt. Utility Model Content

[0007] The utility model aims to solve the problem that when using the existing stepless variable frequency winch to replace the belt, the steel wire rope needs to be loosened several times to complete the work of replacing the new belt, and the belt replacement time is long.

[0008] The utility model provides the following technical solution: a winch for replacing the belt of a belt conveyor, comprising a drum frame and a drum, the drum being mounted on a rotating shaft of the drum frame, the rotating shaft being connected to a torque output mechanism, the drum being driven to rotate by the torque output mechanism, the drum being connected to a forward steel wire rope wound in a forward direction and a reverse steel wire rope wound in a reverse direction, the forward steel wire rope and the reverse steel wire rope being unfolded toward the same side of the drum.

[0009] Furthermore, an annular baffle is fixed on the drum, which separates the drum into two left and right cylinder bodies, and the forward wire rope and the reverse wire rope are respectively wound around the left and right cylinder bodies.

[0010] Furthermore, it also includes a first fixed pulley and a second fixed pulley, the forward wire rope is connected to the belt after being reversed by the first fixed pulley, and the reverse wire rope is connected to the belt after being reversed by the second fixed pulley.

[0011] Furthermore, the torque output mechanism includes a motor and a reducer.

[0012] Furthermore, the reel frame and the torque output mechanism are mounted on the same base.

[0013] Furthermore, the baffle is centrally arranged on the reel.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] The following is a comparison of the steps in the use of the winch for replacing the belt conveyor belt of the utility model and the original stepless variable frequency winch:

[0016] The original stepless variable frequency winch: loosen the wire rope - connect the wire rope with the old belt - drag the old belt - remove the wire rope - loosen the wire rope; each cycle has five steps;

[0017] The utility model is a winch for replacing the belt of a belt conveyor:

[0018] Forward wire rope drags the old belt (loosen the reverse wire rope) - remove the forward wire rope (connect the reverse wire rope to the old belt) - reverse wire rope drags the old belt (loosen the forward wire rope). Each cycle has three steps;

[0019] During on-site use, the effect was good and achieved the expected purpose. The specific effects are as follows:

[0020] 1. By welding a baffle on the original winch drum, the original winch drum is "split into two", and the two coils of wire rope are wound "one forward and one reverse", so that the purpose of winding and releasing the wire rope at the same time is achieved.

[0021] 2. The production and application of the new winch not only saves the time of loosening the wire rope separately, but also saves half the time of connecting and removing the wire rope and the old belt, greatly shortens the time of replacing the belt, improves the work efficiency of maintenance personnel, and minimizes the impact time of the production system.

[0022] 3. The winch used to replace the conveyor belt has a wide range of applications. It is not only suitable for the replacement of various small and medium-sized belts, but also for the replacement of large belts. It can greatly improve the replacement efficiency and save replacement time; it ensures the normal organization of daily production and contributes to the smooth completion of production tasks throughout the year.

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0026] like Figure 1 As shown: A winch for replacing the belt of a belt conveyor includes a drum frame 1 and a drum 2. The drum 2 is installed on the rotating shaft of the drum frame 1, and the rotating shaft is connected to the torque output mechanism. The drum 2 is driven to rotate by the torque output mechanism. The torque output mechanism includes a motor 8 and a reducer 9. A forward wire rope 3 wound in a forward direction and a reverse wire rope 4 wound in a reverse direction are connected to the drum 2, achieving the purpose of winding and loosening the wire rope at the same time. The forward wire rope 3 and the reverse wire rope 4 are unfolded to the same side of the drum 2.

[0027] An annular baffle 5 is fixed on the drum 2, which is welded to the drum 2 and is centrally arranged on the drum 2. The baffle 5 separates the drum 2 into two left and right cylinder bodies, and the forward wire rope 3 and the reverse wire rope 4 are respectively wound around the left and right cylinder bodies.

[0028] The winch also includes a first fixed pulley 6 and a second fixed pulley 7. The forward wire rope 3 is connected to the belt after being deflected by the first fixed pulley 6, and the reverse wire rope 4 is connected to the belt after being deflected by the second fixed pulley 7. The first fixed pulley 6 and the second fixed pulley 7 are installed in conjunction with each other. Since the wire rope unwinding and rewinding steps are performed simultaneously, to prevent cross-operation and ensure the safety of maintenance personnel, two pulleys are fixed to the wall opposite the winch. Maintenance personnel use the pulleys to safely drag the wire rope.

[0029] The drum frame 1 and the torque output mechanism are mounted on the same base 10, making it easy to move the drawworks underground.
